Joules to Foot-Pounds per Second Conversion

Converting Joules (J) to Foot-Pounds per Second (ft⋅lbf/s) is a common energy and power conversion. 1 J equals 0.737562 ft⋅lbf/s. For example, 100 J is equal to 73.756212 ft⋅lbf/s.

Quick Mental Math: Joules to Foot-Pounds per Second

If 1 joule is released in 1 second, it is about 0.7376 foot pounds per second.

Why is converting Joules to Foot-Pounds per Second tricky?

joules to foot pounds per second mixes energy with power, so the missing time step is the trap: the same energy gives different power over 1 second and 1 hour.

Quick Reference Values

1 J = 0.737562 ft⋅lbf/s. 5 J = 3.687811 ft⋅lbf/s. 10 J = 7.375621 ft⋅lbf/s. 25 J = 18.439053 ft⋅lbf/s. 50 J = 36.878106 ft⋅lbf/s. 100 J = 73.756212 ft⋅lbf/s.

What is Joules?

Joules (J) is a unit of energy and power. The joule is the SI unit of energy defined as the work done when a force of one newton moves an object one meter in the direction of the force. It equals one kilogram meter squared per second squared (kg·m²/s²). This definition aligns with the International System of Units as standardized by the BIPM [bipm-si-brochure]. The joule is named after James Prescott Joule, a 19th-century physicist who studied energy conservation. It was officially adopted as a unit of energy by the CGPM in 1948 to unify energy measurement standards internationally [cgpm-resolutions]. Joules are used worldwide in physics, engineering, and electrical industries to quantify energy, work, and heat. Countries using the SI system, including those in Europe, Asia, and the Americas, rely on joules for scientific and industrial applications [nist-si-guide].

What is Foot-Pounds per Second?

Foot-Pounds per Second (ft⋅lbf/s) is a unit of energy and power. Foot-pounds per second is a power unit representing one foot-pound of work performed every second. Since one foot-pound equals 1.355818 joules, 1 ft·lb/s equals approximately 1.355818 watts. It measures instantaneous mechanical power in imperial units [nist-cuu]. This unit arose from the combination of foot-pound work units with seconds to measure power in mechanical engineering, standardized alongside other imperial units in the 19th century. It reflects the rate of energy transfer [nist-cuu]. Foot-pounds per second is used in the United States in fields like mechanical engineering and automotive industries. It helps specify power output and torque rates where imperial units predominate [nist-cuu].

Common Misspellings

People often search for this conversion using these alternate spellings: joule, joul, jouls, juls, foot pounds per second, ft lb per sec, foot lb/sec, ft-lb per second. All of these refer to the Joules to Foot-Pounds per Second conversion.
